ADDITIONAL MODES
The AD1939 offers several additional modes for board level
design enhancements. To reduce the EMI in board level design,
serial data can be transmitted without an explicit BCLK. See
Figure 27 for an example of a DAC TDM data transmission
mode that does not require high speed DBCLK. This configura-
tion is applicable when the AD1939 master clock is generated
by the PLL with the DLRCLK as the PLL reference frequency.
To relax the requirement for the setup time of the AD1939 in
cases of high speed TDM data transmission, the AD1939 can
latch in the data using the falling edge of DBCLK. This effec-
tively dedicates the entire BCLK period to the setup time. This
mode is useful in cases where the source has a large delay time
in the serial data driver. Figure 28 shows this pipeline mode of
data transmission.
Both the BCLK-less and pipeline modes are available on the
ADC serial data port.
